Highly Cited Methodology Update: January 2013
We have updated our Highly Cited Researchers (HCR) methodology processes for identifying the world's most highly-cited authors and institutions. This update begins first with an analysis of the most highly-cited papers, and is followed by a review of those individuals who have authored or co-authored the greatest number of these documents.

The analysis now covers a 10-year moving window, with citations counted over an additional year, so every paper is available for citation for at least 12 months. Articles and reviews from the Web of ScienceSM are the primary documents. Once someone is recognized as being highly cited by Thomson Reuters, he/she will retain that designation through the future, regardless of changes to citation influence in future years.
